  • Display remarkably accurate fish size measurements in easy-to-understand graph form*

    The FCV-2100 measures the size and distribution of fish in the selected school, and displays this information in a graph that can be understood at a glance. TruEcho CHIRP™ technology has improved the accuracy and reliability of fish size measurements and graphs.

    * Fish length is a reference value calculated from reflection intensity.
  • Simultaneously displays fish size measurements in three locations

    The FCV-2100 can measure and display fish sizes in three locations at the same time. This allows you to compare and analyze fish size and school composition, which makes for more efficient fishing, such as aiming for fish of a particular size.

  • Simple operation with trackball and InstantAccess bar™

    The FCV-2100 can be operated easily and quickly with its trackball. The screen header also contains Range, Shift, Sensitivity, Image Feed, and Display Mode menus that can be immediately accessed when required. Other functions can also be accessed immediately by setting them in the InstantAccess bar™ as desired*.

    * Up to 10 icons can be set in the InstantAccess bar™
  • Still images and echo data can be recorded and played back

    A maximum of 99 still images can be saved on the processor unit. The maximum number that can be saved externally depends on the capacity of the external recording medium*. Echo data can also be saved to an external medium with a capacity of 500 GB or more*.

    * Optional
  • Checking past images with the convenient scroll-back mode

    By scrolling the screen back, you can review past images.
  • Makes your fishing operation more efficient

    By identifying the approximate size of the targeted fish beforehand, the FCV-2100 enables selective fishing, making fishing operations more efficient.
  • Can be connected to an external fish finder (DFF3/DFF1-UHD network fish finder*)

    Up to three search responses at different frequencies can be displayed on one screen. The response for each type of fish can be seen at a glance, which helps to identify species.

    * DFF3/DFF1-UHD network fish finders are sold separately. Only one can be connected.
  • Easy to install compact transducer

    The transducer is 16 cm in diameter and easy to install in the hull.
  • Connecting external sensors provides various functional add-ons

    • Bottom discrimination function displays the seabed composition both graphically and in color*
    * Requires an externally connected network fish finder (DFF1-UHD) or designated transducer.
    • ACCU-FISH™ function* gives the size of an individual fish at a glance*
    * Requires an externally connected network fish finder (DFF3/DFF1-UHD) or an ACCU-FISH™ compatible transducer.
    • Stable searching with heaving correction function*
      The heaving (up and down motion of a ship) corrective function enables the shape of the seabed to be displayed stably even in rough sea.
    * Requires connection of a Satellite Compass™.
